TECHNICAL FIELD

The present disclosure relates to integrating audio into a multi-view interactive digital media representation.

DESCRIPTION OF RELATED ART

With modern computing platforms and technologies shifting towards mobile and wearable devices that include camera sensors as native acquisition input streams, the desire to record and preserve moments digitally in a different form than more traditional two-dimensional (2D) flat images and videos has become more apparent. Traditional digital media formats typically limit their viewers to a passive experience. For instance, a 2D flat image can be viewed from one angle and is limited to zooming in and out. Consequently, traditional digital media formats, such as 2D flat images, do not easily lend themselves to reproducing memories and events with high fidelity. In addition, 2D videos are usually limited to a set playback of visual data from a particular viewpoint and a corresponding fixed audio track.

As technology has progressed, various three-dimensional (3D) media formats have developed, such as multi-view interactive digital media representations. Examples of these multi-view interactive media representations include surround views, multiview images, and 3D data formats. In these multi-view interactive digital media representations, a user can control how to view the image data. For instance, the user can navigate around various objects and select a viewpoint from which to view the image data.

A problem in the presentation of multi-view interactive digital media representations is how to include audio information in the viewing process. Although image data and audio information may be recorded simultaneously, a user may choose to view the images in a different order than they were acquired during the recording process. Because a user may navigate through the images in the captured multi-view interactive digital media representation in any order, the displayed visual representation of the scene may not be synchronized with playback of the recorded audio. Accordingly, there is a need for improved mechanisms and processes for integrating audio into a multi-view interactive digital media representation.

Overview

Provided are various mechanisms and processes relating to integrating audio into a multi-view interactive digital media representation.

In one aspect, which may include at least a portion of the subject matter of any of the preceding and/or following examples and aspects, one process includes retrieving a multi-view interactive digital media representation that includes numerous images fused together into content and context models. The process next includes retrieving and processing audio data to be integrated into the multi-view interactive digital media representation. A first segment of audio data may be associated with a first position in the multi-view interactive digital media representation. In other examples, a first segment of audio data may be associated with a visual position or the location of a camera in the multi-view interactive digital media representation. The audio data may be played in coordination with the multi-view interactive digital media representation based on a user's navigation through the multi-view interactive digital media representation, where the first segment is played when the first position or first visual position is reached.

In another aspect, which may include at least a portion of the subject matter of any of the preceding and/or following examples and aspects, a computer readable medium for integrating audio into a multi-view interactive digital media representation includes computer code for retrieving a multi-view interactive digital media representation that includes numerous images fused together into content and context models. The computer readable medium also includes computer code for retrieving and processing audio data to be integrated into the multi-view interactive digital media representation. Computer code for processing the audio data includes segmenting the audio data into a first segment and a second segment and associating the first segment with a first position in the multi-view interactive digital media representation and the second segment with a second position in the multi-view interactive digital media representation. The computer readable medium further includes computer code for playing the audio data in coordination with the multi-view interactive digital media representation based on a user's navigation through the multi-view interactive digital media representation, where the first segment is played when the first position in the multi-view interactive digital media representation is depicted and the second segment is played when the second position in multi-view interactive digital media representation is depicted.

In yet another aspect, which may include at least a portion of the subject matter of any of the preceding and/or following examples and aspects, a process for integrating audio into a multi-view interactive digital media representation includes retrieving a multi-view interactive digital media representation that includes a plurality of images fused together into a three dimensional model that is navigable by a user. The process further includes retrieving and processing audio data to be integrated into the multi-view interactive digital media representation. Processing the audio data includes segmenting the audio data into a first segment and a second segment and associating the first segment with a first position in the multi-view interactive digital media representation and the second segment with a second position in the multi-view interactive digital media representation. Next, the process includes playing the audio data in coordination with the multi-view interactive digital media representation based on a user's navigation through the multi-view interactive digital media representation. In particular, the first segment is played when the first position in the multi-view interactive digital media representation is depicted and the second segment is played when the second position in multi-view interactive digital media representation is depicted.

These and other embodiments are described further below with reference to the figures.

DETAILED DESCRIPTION

Reference will now be made in detail to some specific examples of the invention including the best modes contemplated by the inventors for carrying out the invention. Examples of these specific embodiments are illustrated in the accompanying drawings. While the invention is described in conjunction with these specific embodiments, it will be understood that it is not intended to limit the invention to the described embodiments. On the contrary, it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.

For example, the techniques of the present invention will be described in the context of particular audio segments and components. However, it should be noted that the techniques of the present invention can apply to one or more of any variety of different audio segments and components. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Particular example embodiments of the present invention may be implemented without some or all of these specific details. In other instances, well known process operations have not been described in detail in order not to unnecessarily obscure the present invention.

Various techniques and mechanisms of the present invention will sometimes be described in singular form for clarity. However, it should be noted that some embodiments include multiple iterations of a technique or multiple instantiations of a mechanism unless noted otherwise. For example, a system uses a processor in a variety of contexts. However, it will be appreciated that a system can use multiple processors while remaining within the scope of the present invention unless otherwise noted. Furthermore, the techniques and mechanisms of the present invention will sometimes describe a connection between two entities. It should be noted that a connection between two entities does not necessarily mean a direct, unimpeded connection, as a variety of other entities may reside between the two entities. For example, a processor may be connected to memory, but it will be appreciated that a variety of bridges and controllers may reside between the processor and memory. Consequently, a connection does not necessarily mean a direct, unimpeded connection unless otherwise noted.

Various three-dimensional (3D) media formats have developed with advances in technology, such as multi-view interactive media representations. These multi-view interactive digital media representations include formats such as surround views, multiview images, and 3D data formats. In these multi-view interactive digital media representations, a user can control how to view the image data. For instance, the user can navigate around various objects and select a viewpoint from which to view the image data.

Because users can navigate around various objects within multi-view interactive digital media representation, one problem is how to include audio information in this viewing process. Although image data and audio information may be recorded simultaneously, a user may choose to view the images in a different order than they were acquired during the recording process. Because a user may navigate through the images in the captured multi-view interactive digital media representation in any order, the displayed visual representation of the scene may not be synchronized with playback of the recorded audio. Various embodiments described herein relate to improved mechanisms and processes for integrating audio into a multi-view interactive digital media representation.

As described above, a multi-view interactive digital media representation can take numerous forms within the scope of this disclosure. For instance, a multi-view interactive digital media representation may include a surround view, multi-view image, or three dimensional model. Surround views are described in more detail with regard to U.S. patent application Ser. No. 14/530,669 by Holzer et al., filed on Oct. 31, 2014, titled “Analysis and Manipulation of Images and Video for Generation of Surround Views,” which is incorporated by reference herein in its entirety and for all purposes. According to various embodiments described therein, a surround view provides a user with the ability to control the viewpoint of the visual information displayed on a screen. In addition, a surround view presents a user with an interactive and immersive active viewing experience.

According to various embodiments, the data used to generate a surround view can come from a variety of sources. In particular, data such as, but not limited to, two-dimensional (2D) images can be used to generate a surround view. These 2D images can include color image data streams such as multiple image sequences, video data, etc., or multiple images in any of various formats for images, depending on the application. Another source of data that can be used to generate a surround view includes location information. This location information can be obtained from sources such as accelerometers, gyroscopes, magnetometers, GPS, WiFi, IMU-like systems (Inertial Measurement Unit systems), and the like. Yet another source of data that can be used to generate a surround view can include depth images. These depth images can include depth, 3D, or disparity image data streams, and the like, and can be captured by devices such as, but not limited to, stereo cameras, time-of-flight cameras, three-dimensional cameras, three-dimensional capture devices, a combination of devices, a combination of multidimensional capture devices, and the like.

According to one example, gathered data can be fused together. In some embodiments, a surround view can be generated by a combination of data that includes both 2D images and location information, without any depth images provided. In other embodiments, depth images and location information can be used together. Various combinations of image data can be used with location information, depending on the application and available data.

In the present example, the data that has been fused together is then used for content modeling and context modeling. According to various examples, the subject matter featured in the images can be separated into content and context. The content can be delineated as the object of interest and the context can be delineated as the scenery surrounding the object of interest. According to various embodiments, the content can be a three-dimensional model, depicting an object of interest, although the content can be a two-dimensional model in some embodiments. Furthermore, in some embodiments, the context can be a two-dimensional model depicting the scenery surrounding the object of interest. Although in many examples the context can provide two-dimensional views of the scenery surrounding the object of interest, the context can also include three-dimensional aspects in some embodiments. For instance, the context can be depicted as a “flat” image along a cylindrical “canvas,” such that the “flat” image appears on the surface of a cylinder. In addition, some examples may include three-dimensional context models, such as when some objects are identified in the surrounding scenery as three-dimensional objects. In various embodiments, the models provided by content modeling and context modeling can be generated by combining the image and location information data.

According to various embodiments, context and content of a surround view are determined based on a specified object of interest. In some examples, an object of interest is automatically chosen based on processing of the image and location information data. For instance, if a dominant object is detected in a series of images, this object can be selected as the content. In other examples, a user specified target can be chosen. It should be noted, however, that a surround view can be generated without a user specified target in some applications.

According to various embodiments, one or more enhancement algorithms can be applied. In particular example embodiments, various algorithms can be employed during capture of surround view data, regardless of the type of capture mode employed. These algorithms can be used to enhance the user experience. For instance, automatic frame selection, stabilization, view interpolation, filters, and/or compression can be used during capture of surround view data. In some examples, these enhancement algorithms can be applied to image data after acquisition of the data. In other examples, these enhancement algorithms can be applied to image data during capture of surround view data.

Although various embodiments described herein may include references to surround views, other types of multi-view interactive digital media representations are also intended to be included. For instance, representations such as a multi-view image, three dimensional model, or other formats can be integrated with audio data. For instance, a multi-view image or three dimensional model may include navigation capabilities, views of the subject matter from various viewpoints, etc. In these representations, content and context need not necessarily be separated.

With reference to FIGS. 1A-1B, shown is an example of a navigation through a multi-view interactive digital media representation on a mobile device. Specifically, a mobile device 100 is shown at two different navigation points. In FIG. 1A a view of a multi-view interactive digital media representation at a first position 102 is shown. A car is featured as content 106, and some trees are shown as context 104. In some embodiments, the multi-view interactive digital media representation can be played automatically from this position 102 if the user presses the autoplay button 112. Such automatic play may include a predetermined navigation through the multi-view interactive digital media representation. In other embodiments, the autoplay button 112 may play an audio track while the user navigates manually through the multi-view interactive digital media representation. Additional buttons or navigation tools can also be included.

In the present example, various navigations are available to the user. For instance, the user can browse through the multi-view interactive digital media representation by swiping around the trees using navigation 102. This may involve a rotation around the trees to reach a new viewpoint behind the car. The user can also browse through the multi-view interactive digital media representation by dragging the car to the left of the screen using navigation 108. In this case, the car would move to the left and the scenery around the car would also shift relative to the car. Yet another example of browsing includes the user swiping in the direction of navigation 110 to move the viewpoint of the scene. The car would then be viewed at a different angle and the scenery surrounding this viewpoint would also shift. Endless possibilities for navigating through the multi-view interactive digital media representation are possible.

In the present example, pressing the autoplay button 112 shows the car moving from right to left in the scene and the scenery moving relative to the car. FIG. 1B shows a view at second position 116 once the scene has progressed 114 in the automatic playback. As shown, the content 106 has shifted relative to the context 104. Although the present example shows the visual playback of the scene based on the user's navigation through the multi-view interactive digital media representation, the audio data accompanying this visual playback will be described in more detail below with particular reference to FIGS. 3A-3C. It should be noted that audio data may be attached to either position of an object or the position of a capture device. Video object position refers to position of an object such as a thing or entity or person in a surround view. Video capture position refers to the position of the capture device. Both can be used for triggering playback and/or positioning the audio data. Position may also include different angles, perspectives, geographic locations, etc. According to various embodiments, a surround view of a piano may be depicted where the keys of the piano are the dominant elements and an audio file is attached to any piano key location. Therefore, someone can play a piano by touching the corresponding keys and navigating through the piano keys in the surround view.

In other examples, a panoramic surround view includes a car that is driving by. In the background there are trees with chirping birds and the ocean with waves crashing on the shore. The audio data that is recorded is decomposed into the sound of the car, the sound of the birds, and the sound of the waves and the audio files are attached to the locations of those elements in the visual data. In still other examples, a surround view of a person includes a person making a face at a specific camera position within the surround view. An audio file is automatically played when that camera position is reached while navigating through the surround view.

In the present example, a particular multi-view interactive digital media representation is depicted with a car as content 106 and the trees as context 104. With reference to FIG. 2 , shown is a depiction of content and context in the multi-view interactive digital media representation described with regard to FIGS. 1A-1B. In particular, FIG. 2 illustrates one example of separation of content and context in a scene 200. In the present example, the viewer 212 is shown viewing or capturing images of an object of interest, such as the car shown.

According to various embodiments, the digital visual data included in a scene 200 can be, semantically and/or practically, separated into content 206 and context 210, especially in the implementation of surround views. According to particular embodiments, content 206 can include the object(s), person(s), or scene(s) of interest while the context 210 represents the remaining elements of the scene surrounding the content 206. In the present example, the object 202 is a car. This object 202 constitutes the content 206 of the scene 200. The trees in the scenery 208 constitute the context. In some examples, a surround view may represent the content 206 as three-dimensional data, and the context 210 as a two-dimensional panoramic background. In other examples, a surround view may represent both the content 206 and context 210 as two-dimensional panoramic scenes. In yet other examples, content 206 and context 210 may include three-dimensional components or aspects. In particular embodiments, the way that the surround view depicts content 206 and context 210 depends on the capture mode used to acquire the images.

In some examples, such as but not limited to: recordings of objects, persons, or parts of objects or persons, where only the object, person, or parts of them are visible, recordings of large flat areas, and recordings of scenes where the data captured appears to be at infinity (i.e., there are no subjects close to the camera), the content 206 and the context 210 may be the same. In these examples, the surround view produced may have some characteristics that are similar to other types of digital media such as panoramas. However, according to various embodiments, surround views include additional features that distinguish them from these existing types of digital media. For instance, a surround view can represent moving data. Additionally, a surround view is not limited to a specific cylindrical, spherical or translational movement. Various motions can be used to capture image data with a camera or other capture device. Furthermore, unlike a stitched panorama, a surround view can display different sides of the same object.

With reference to FIG. 3A, shown is an example of a process for integrating audio with a multi-view interactive digital media representation. In particular, the process 300 includes retrieving a multi-view interactive digital media representation at 301. As described above, the multi-view interactive digital media representation can include formats such as a surround view, multi-view image, or three dimensional model. In some examples, the multi-view interactive digital media representation includes numerous images fused together into content and context models, where the content model includes an object and the context model includes scenery surrounding the object.

In the present example, the process 300 continues by retrieving audio data to be integrated into the multi-view interactive digital media representation at 303. The audio data can be obtained in a variety of ways depending on the application or desired effect. For instance, an audio stream can be recorded together (i.e., at the same time) with the recording of the visual data included in the multi-view interactive digital media representation. In another example, an audio stream can be recorded separately from the visual data. One or more audio recordings can be created to use with the visual data. In other examples, pre-recorded audio files can be used. For instance, the user may have recorded this audio data at an earlier time or may use one or more existing audio files from the Internet or other sources. Some examples of audio files that may be used include musical recordings, sound effects, ambient noise or sounds, voice recordings, etc. A variety of effects can be applied in the processing step. Examples of effects include changing the pitch or introducing an echo effect.

In the present example, the process 300 further includes processing the audio data at 305. In particular, after an audio file has been recorded or selected it has to be processed in order to be integrated into the format of the multi-view interactive digital media representation. Several options for processing are possible, one or more of which can be combined in some examples. In one example, the recorded/selected audio file is directly used without processing. In another example, the recorded/selected audio file is decomposed into different components. For instance, voices are separated from background sounds, and different sound sources are separated (e.g. cars, ocean, birds, talking). This decomposition can be implemented in a variety of ways. One way includes using independent component analysis. Once the audio file is decomposed into different components, the separate audio streams are then either presented to the user for further selection and positioning or automatically assigned to locations in the multi-view interactive digital media representation corresponding to where they originated (i.e. locations of the original audio if the audio was recorded with the video). More details relating to the positioning of audio streams within the multi-view interactive digital media representation are discussed below with regard to audio playback at 307. Additionally, a particular example of processing audio data is described in conjunction with FIG. 3B.

Once the audio data is processed, the audio data is then played in coordination with the multi-view interactive digital media representation at 307. The playback of the audio data can be done in several ways. In one example, the audio data is played once as soon as the multi-view interactive digital media representation is loaded and displayed. In some instances, the audio data is played while the user navigates through the multi-view interactive digital media representation and the audio data is played at original speed during this navigation, independent of navigation direction or speed. In other instances, the audio data is played while the multi-view interactive digital media representation follows a predetermined auto play sequence. In yet other instances, audio and image data are initially played (once or multiple times) without user interaction available. Once this initial play is over, the user can manually navigate through the multi-view interactive digital media representation. In another example, the audio data is played repeatedly as soon as surround view is loaded and displayed. In some instances, the audio data is played repeatedly whether the user navigates the multi-view interactive digital media representation or the multi-view interactive digital media representation plays through an automatic playback sequence.

In some examples, the audio data is played in conjunction with navigation through the multi-view interactive digital media representation. For instance, navigating in one direction plays the audio forward and navigating in the other direction plays the audio backwards. In some instances, the speed of audio playback corresponds to navigation speed.

Another option for audio playback includes playing the audio data when a “Play” button is pressed or otherwise selected. For instance, as shown in FIGS. 1A-1B, an autoplay button 112 can be located in a predefined position in a user interface and selection of this button can begin audio playback. In another instance, a play button can be positioned in a manner to follow the corresponding image data. In this instance, the play button can either be visible or invisible to the user. According to various embodiments, a play button can have standard shape (e.g., triangular) or follow the shape of a specific object/region in the scene (e.g. a bird, a car, etc.).

In other embodiments, audio playback is based on navigation through the multi-view interactive digital media representation. In one example, audio is played when a certain position/frame of the multi-view interactive digital media representation is reached during navigation, whether manual or automatic. In some examples, audio data is associated with specific positions or frames in the multi-view interactive digital media representation. The closer the user navigates towards these positions or frames, the louder the corresponding audio plays. In particular examples, audio data can be “attached” to a 3D location in a scene and the volume of the audio playback depends on the distance and orientation of the current view point of the visualization. Specifically, the sound volume of an audio playback increases if the navigation location approaches the 3D location of the audio data. Similarly, the volume increases if the viewing direction of the navigation is oriented towards the location of the audio data and the volume decreases if the viewing direction of the navigation is oriented away from the location of the audio data.

Referring to FIG. 4 , shown is an example representation of a multi-view interactive digital media representation where the navigation location varies with respect to different objects in the scene 400. The object 402 moving in direction 404 may have associated sounds such as car revving and motor sounds. At navigation location 408, the viewpoint is directed towards the object 402 and the sound of the object 402 would be louder than when the navigation location is at any of the other locations 410, 412, or 414 as shown. When the navigation location 414 is selected, the sounds associated with the scenery 406 may be more audible, such as trees swaying in the wind. From this location, sounds from both the scenery 406 and the object 402 might be audible. In contrast, at navigation location 410, the scenery 406 sounds may not be audible and the sounds of the object 402 may be played at a lower volume because the location 410 is further away from the object 402.

Referring back to FIG. 3A, in some embodiments, the volume, pitch, and/or playback speed of audio data at 307 is dependent upon user input. For instance, swiping speed on a touch screen or by a mouseover or force applied to a force-sensitive touch pad can affect volume, pitch, and/or playback speed of audio data in some examples. In addition, rotational velocity, as measured by an inertial sensor, of a mobile device can affect volume, pitch, and/or playback speed of audio data in some examples.

Another option for audio playback is to play background music (e.g. a song) or sound effects while the user navigates through a multi-view interactive digital media representation. In some embodiments, the type or style of the background music can be correlated with the occurrence and strength of visual filters. For instance, detection of a beat in the music increases the strength of a filter or a different filter is applied if the style or type of the music changes. In some examples, the filters can be applied to correspond to the chosen background music. In other examples, the background music can be chosen based on any filters or effects included in the visual file. For instance, certain filters that make the visuals dark and murky may cause selection of darker songs or sound effects.

In some examples, audio playback in 307 can also occur during automatic playback of the multi-view interactive digital media representation. For instance, automatic playback may be initiated by user action such as selection of an autoplay button, as shown in FIGS. 1A-1B, automatically without user action, or in a video export. In some embodiments, one or more multi-view interactive digital media representations can be exported and synchronized with background music. Specifically, certain types of music can be correlated with certain types of multi-view interactive digital media representations. For instance, calm music can be correlated with scenic multi-view interactive digital media representations. In addition, the playback speed of a multi-view interactive digital media representation can be correlated with the type of music. In particular, calm music can be combined with slow playback of a multi-view interactive digital media representation.

In some embodiments, a switch between multi-view interactive digital media representations or a switch in the type of visualization or playback effects within a certain multi-view interactive digital media representation can happen when the style of the music changes or in synchronization with the occurrence of certain instruments or beats. In some examples, a change in the visualization direction within a multi-view interactive digital media representation occurs in synchronization with certain instruments or beats. In other examples, a change in the playback speed of the visual data may occur if the type of music changes or in synchronization with a certain instrument or beat. In yet other examples, the occurrence and strength of visual filters can correspond to the type of music and the occurrence of certain instruments. For instance, a beat increases the strength of a filter or a different filter is applied if the style or type of the music changes. In some embodiments, the user can define where and when the multi-view interactive digital media representations are switched and/or how the playback changes during automatic playback.

In particular embodiments, a combination of automatic playback and interactive navigation is possible. For example, a specific song can be played in the background and the current visible multi-view interactive digital media representation is switched at certain locations within the song, but the user is able to interactively navigate through the currently visible multi-view interactive digital media representation. In a converse example, a song can be played in the background and the user can switch between different multi-view interactive digital media representations, but the multi-view interactive digital media representations are autoplayed.

Although the above example describes various embodiments relating to integrating audio with a multi-view interactive digital media representation, FIGS. 3B and 3C include examples of particular embodiments of methods for processing audio data and playing the audio data in coordination with a multi-view interactive digital media representation. With reference to FIG. 3B, shown is an example of a particular method for processing an audio file to be integrated with a multi-view interactive digital media representation as referred to in step 305 of FIG. 3A. In the present example, processing the audio data 305 includes segmenting the audio data into a first segment and a second segment at 311. According to various embodiments, the first segment and second segment can be segmented from the audio data using independent component analysis. In the present example, the first segment includes a first set of sound sources and the second segment includes a second set of sound sources. For instance, the first set of sound sources may include voices and the second set of sound sources may include background noises. In another instance, the first segment may include sounds occurring near a first position in the multi-view interactive digital media representation, and the second segment may include sounds occurring near a second position in the multi-view interactive digital media representation.

Next, the first segment is associated with a first position in the multi-view interactive digital media representation at 313 and the second segment is associated with a second position in the multi-view interactive digital media representation at 315. In some instances, the first position is the same as the second position. In these cases, the first segment and second segment will overlap when played. In some examples, the first position and second position are located in separate places, but at least a portion of the first segment and second segment may overlap when played.

With reference to FIG. 3C, shown is a particular example of a process for playing an audio file integrated with a multi-view interactive digital media representation. According to various embodiments, the audio data is played back based on a user's navigation through the multi-view interactive digital media representation. In some examples, the first segment is played when the first position in the multi-view interactive digital media representation is played and the second segment is played when the second position in multi-view interactive digital media representation is played. In particular, playing the audio data 307 includes receiving a request to play a multi-view interactive digital media representation from the first position at 321. In response, the first segment of audio data is played when the multi-view interactive digital media representation is played from the first position at 323. Next, a request is received to play the multi-view interactive digital media representation from the second position at 325. In response, the second segment of audio data is played when the multi-view interactive digital media representation is played from the second position at 327.

According to various embodiments, the requests to navigate to the first position and second position can be made in numerous ways. In one example, a user's navigation through the multi-view interactive digital media representation includes selecting automatic playback, where automatic playback triggers play of a predetermined navigation through the multi-view interactive digital media representation. This predetermined navigation includes a set sequence of views and audio data that includes navigation to the first position and the second position. In another example, a user's navigation through the multi-view interactive digital media representation includes navigating to the first position and navigating to the second position. As described above with regard to FIG. 1A, the user can navigate to these positions through user input such as swiping a screen, manipulating a mouse or cursor, or tilting or otherwise moving a mobile device. In some embodiments, the first segment plays when the user navigates to the first position, and the volume of the first segment decreases as the user navigates away from the first position.
